HD Radio: So we already know AM radio is not available. On the 3 specs page it says "FM/Internet radio" but on the Model S specs it specifically mentions HD Radio. I wonder if it was an oversight or it just won't be available. There are a handful of HD2 stations around that play a great mix with no commercials, and HD2 stations do not stream online. USB Ports: The Premium package comes with 4 USB ports: 2 front, and 2 rear. Do the rear ports offer a data connection or just charging? It would be nice to plug a small MP3 USB stick in one of the rear ports and leave the fronts open for phone charging (or a dash cam, etc).
